Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592576, here are decompositions:

19 + 31592557 = 31592576
109 + 31592467 = 31592576
139 + 31592437 = 31592576
199 + 31592377 = 31592576
229 + 31592347 = 31592576
373 + 31592203 = 31592576
523 + 31592053 = 31592576
577 + 31591999 = 31592576

Showing the first eight; more decompositions exist.
